133892-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133892-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,9 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133892-89:
(8*1)+(7*3)+(6*3)+(5*8)+(4*9)+(3*2)+(2*8)+(1*9)=154
154 % 10 = 4
So 133892-89-4 is a valid CAS Registry Number.
